为 Python/Matplotlib 禁用 OpenGL

Question

我正在学习 Python 课程，为此我在虚拟机中安装了 Arch Linux。当我使用 Matplotlib.pyplot 绘制事物（x vs y）时，我得到了一堆错误。

当我关闭对 VM 的 3D 支持时，它只需要 openGL。我的脚本确实创建了一个情节（空canvas）但没有一行。

我觉得不用openGL也能画一些线吧？如何解决这个问题...

编辑：我认为这是一个 VirtualBox 错误加上我的 Python 代码中的一个错误。我实际上可以获得带有最后出现的错误消息的好图表。在最新版本的 VirtualBox 中，我不再收到错误消息。感谢您的建议。

因此，尽管存在所有错误，但实际上我从未遇到过任何无法正常工作的情况，事实上我没有看到图表并不是因为原始 post 中的错误。这是另外一回事，我想这与 mpl 无关，更多的是与 VirtualBox 中缺乏 3D 加速有关。
